My landlady is setting off a bug bomb in my apartment today. I'm not super pleased with this, but here we are.
I have a leopard gecko and a ball, they have been moved to a friends house. My question is how long should I wait till I bring them back into my house?

I believe the container suggests around 4 hours for people but reptiles are different and sensitive to airborne stuff. They are safe and happy where they are currently but I'd like to have my babies back asap. Any advice would be welcomed.
